Ups, I completely forgot about Josh's patch, thanks for the reminder.
Nevermind, the intention of the patch set was to get agreement on the
approach of the qpnp-spmi driver. The rtc is just slightly reworked to
platform driver downstream rtc driver. And last but not least I've used
rtc to test the approach and as a example of PMIC function/peripheral
driver.

I will see what efforts are needed to reuse rtc-pm8xxx.
